I am currently braking with 3 wheels ( the 2 front & passenger rear) I bled the system but the caliper was stiff so I bought a new one but I am still having the same problem
I get oil but it does not seam to have pressure to stop the disk
Any Advise.... Comments
Thanks_DAV 78

Brake !

Did U Change UR Brake Hose ?

 

[david78]

The lines are steel tubing and seem to be clear
the only possibility I can think of is a partially clogged line so disconnecting everything and blowing compressed air into it

 

[vettex2]

sometimes the rubber hoses degrade and cause issues , although this is rare.

David, if your lines are clear,and you are sure you have all the air out of the system, and it still has no pressure to the rear , I would suspect the Master Cylinder

but that would be an issue for 2 wheels if you have a double resevoir
all four if it's a single......perhaps a proportioning valve blockage ?

it very well could be.. I was thinking that its farthest from a weak M/C , less pressure

 

[david78]

I haven't had the time to look into it but I have a day off tomorrow
the master cylinder was replaced and it is under warranty so might change that as well but isn't the driver side the closest?

I thought it was Right Rear... are you absolutely sure the line is clear and all air is purged ? it is possible that its still in the caliper, is that a rebuilt? or like EX said, maybe proportioning valve

To Say the truth, I over bled
it is rebuilt

I blew air into the lines and my all my brakes work now and spent most of the day bleeding the lines of air :thumbsup3:
One other question: my car shuts off when I suddenly brake
thinking my idle is low 600RPMs but I dont know
Opinions????

so it was a blockage in line? ..glad it works now.. is that 600 rpm in gear or park ? I don t recall what carb you have, if its Holley, check your float levels

yeah...will I think it was a blocked line. my car is set at 600 Rpms in park... too low?
I have a Holley 670 (street avenger)
The floats are level it works better when I raise my RPM's but dont know if its the mask or the fix??????

 

[vettex2]

could be idle mixture also

 

[[email protected]]

could be, best way to set it is with a vacuum gauge, adjust mixture screws to get the highest vacuum reading at idle...600 rpm in park is a little low, will drop 100-150 in gear ..

The idle speed for small blocks is usually around 550-600 rpm in DRIVE or about 750 rpm in PARK. Big blocks can be idled down a little lower.

Thanks for the help
ALL IS GOOD!

Some things overlooked when it stalls / dies are stuck EGR, stuck advance curve and leaking power valve. If it's a lock up converter check the lock up switch. These are just in case items...
